GEARING.

SPECIFICATION forming part of Letters Patent No. 7 56,737, dated April5, 1904.

Application filed November 2, 1901. 7 Serial No. 80,875. (No model.)

To aZZ whmn it may concern:

Be it known that I, WILLIAM THORNTON, a citizen of the United States,residing at Chattanooga, in the county of Hamilton and State ofTennessee, (post-office address No. East Seventh street, Chattanooga,Tennessee,) have invented certain new and useful Improvements inGearing; and I do hereby declare the following to be a full, clear, andexact descripti on of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to a gearing, and particularly to an alternatingrotary gearing adapted for use upon washing-machines.

The invention has for an object to improve the construction andarrangement of the gearing and the supporting-standard therefor, so asto retain the parts in accurate mesh in the operation of the machine andto permit the opening of the cover thereof without disarrangement ofsaid parts.

Further objects and advantages of the invention will be hereinafter setforth and the novel features thereof defined by the appended claims.

In the drawings, Figure 1 is a side elevation of the invention appliedto aWashing-machine with parts broken away. Fig. 2 is a detail endelevation, and Fig. 3 is a plan with parts broken away, and Fig. 4 is adetail perspective of the standard.

Like numerals of reference refer to like parts in the several figures ofthe drawings.

In the present application of this invention the tub or suds-box 5 isformed of any suitable shape and may be provided with interior cleats 6upon'the several sides thereof. The tub is shown as supported by legs 7and provided with a cover 8, extending over the entire top of the boxand hinged at one side at 9 9. Upon this cover bearing-brackets 10 and11 are provided to receive the crank-shaft 14:, which is provided at oneend with a balancewheel 15 and at the opposite end with a crankarm 16,secured thereto. The upright standard or support 12 is provided with abaseplate or bearing 13, from which a yoke portion 2 extends upward andis provided at its apex with an upright 3, having a bearing therein toreceive the pivot-pin 21, by means of which the segmental gear 19 ismounted at the top of the standard. This gear is connected with thecrank-arm by means of the pitman 17, secured to said arm at one end by awrist-pin 18 and at the opposite end to the gear 19 by a wrist-pin 20.Extending across the yoke portion of the standard is a crossbar 4,extended laterally from one face of the standard parallel to thebase-plate and having therein a central bearing, between which and thebase-plate 13 the beveled pinion 22 is disposed and pivoted thereon.This pinion is secured to the shaft 24, carrying at its lower end theagitators 23 within the tub or any other suitable device.

In the operation of the invention it will be seen that the power istransmitted from the pitman to the segmental gear between the pivotthereof and the teeth thereon, so as to secure the most desirableleverage, while the driving-shaft and bearing are mounted at the hingedside of the cover or lid, so as to dispose the weight of these parts inthe most convenient position to permit the easy opening of the cover foraccess to the'interior of the tub. It will also be apparent that thenovel construction of the standard herein disclosed provides means forretaining the beveled pinion between the base-plate and the cross-bar ofthe standard, while the segmental gear is pivoted at the upper portionof said standard, so that all of the parts are held in a fixed relationto each other and may be placed upon the machine by an unskilledworkman, while the arrangement of the standard places the axis of thepinion at one side thereof and permits the direct pivoting of thesegmental gear upon the opposite face.

Having described my invention and set forth its merits, what Iclaim, anddesire to secure by Letters Patent, is-

1. In a gearing, a standard comprising a base-plate provided with abearing, a yoke extending vertically from said base-plate and having anintegral cross-bar projected from one side of the yoke at its lowerportion parallel to the base-plate and provided with a central bearingin alinement with the bearing in the base-plate, and a verticalprojection from the apex of the yoke provided with a horizontal bearingin a vertical plane parallel to the bearings in the base-plate andcross-bar. v

2. In a gearing, a standard comprising a base-plate provided with abearing, a yoke extending vertically from said base-plate and havinganintegral cross-bar projected from one side of the yoke at its lowerportion parallel to the base-plate and provided with a central bearingin alinement with the bearing in the base-plate, a vertical projectionfrom the apex of the yoke provided with a horizontal bearing in avvertical plane parallel to the hearings in the base-plate andcross-bar, a

pinion disposed between said plate and cross .5 bar, a segmental gearpivoted upon the vertical projection from-said yoke and meshing at itslower end with said pinion, a driving-shaft, a pitman connecting saiddriving-shaft to said segmental gear between its pivot and the teeththereon.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM THORNTON.
